WLM Workload Manager. HP-UX WLM
provides automatic resource allocation and
application performance management
through the use of prioritized service-level
objectives (SLOs).
WLM daemon See wlmd.
WLM interval The frequency at which
WLM checks for new performance data for
the managed workloads and then adjusts
CPU resource allocations. The length of the
interval is configurable, but defaults to 60
seconds.
wlmd The WLM daemon, which is used to
activate WLM configurations.
wlmpard The WLM global arbiter daemon,
which is used to activate WLM
configurations for cross-partition
management.
wlmemsmon The WLM EMS monitor, which
collects WLM and SLO status information
and then makes that information available
to EMS clients.
workload A collection of processes running
in an nPartition, virtual partition, Integrity
Virtual Machines (Integrity VM) host, PSET,
or FSS group and whose performance is
managed as a single unit. Examples include
the processes that belong to an application
or all the processes owned by a user. A
workload based on PSETs or FSS groups is a
workload group, which is defined in a PRM
structure.
workload group Any group defined in the
prm structure with the groups keyword. A
workload based on PSETs or FSS groups.
You assign critical applications to workload
groups. WLM then manages the
performance of FSS workload groups by
adjusting their CPU resources, while
assigning PSET workload groups whole
cores for their dedicated use. See also
active workload group.
